[Pacemaker] [Patch] An error may occur to be behind with a stop of pingd.

Hi All,

We confirmed the phenomenon that an error generated to be behind with a stop of pingd.

The problem seems to be to be behind with receiving of SIGTERM of pingd until stand_alone_ping processing is completed.

I added the end confirmation of the pingd process to solve this problem.

I attached a patch.
Please take this patch in Pacemaker1.0.

Best Reargds,
Hideo Yamauchi.
